Guys, was this a test? Why did he block me?

I think it's a misunderstanding. I let my guy friend know I'd give him space after a few times he wasn't responding to some of my messages. I get the feeling he may be going through something and wanted to take any pressure off. I made it known I wasn't upset, appreciated our interactions, and hoped to leave our dynamic on good terms. What did I do wrong? We've had communication issues in the past so I was trying to be open with him as we rebuild the friendship and let him know I can understand if he just needs space. I thought I was being a good friend. Instead he blocked me.
